' 2 Claims.

I This invention relates to window cleaners or washers, and particularly to devices of this kind designed for large scale operations such as windowwashing as an occupation, or for washing store windows and the like. I

The main object of the invention is to provide a window cleaner including a housing, a pair of spaced belt-carrying rollers journaled in the housing, one of the rollers being a window contact. roller and being partially protruded from the housing for that purpose, the other or inner roller being a belt carrying and wringer roller, a complemental wringer roller adjustablyspringpressed against the other wrin'ger roller, an endless cleansing or wash belt mounted on the belt carrying rollers and between the inner wringer rollers, a rotary beater journaled in the housing and adapted to contact the outer side of the belt,

and rear plates 9, 9a, secured to the end plates by screws I0. The frontal side of the housing is a water motor in the housing, gear connections for operating the rollers and beater from the water motor, a hollow handle for the housing, the same serving also as a drain pipe for water used, a relatively small feed water pipe or hose extended up through the hollow handle for feeding water under pressure through the water motor for operating the same and for supplying water to the Wash belt.

With the foregoing objects in view, together with such other objects and advantages as may appear from the specification, a preferred embodiment of the invention is shown inthe accompanying drawings, wherein:

Figure 1' is a side elevation of the invention asenclosed in its housing, a portion of the .hous-I Figure 4 is a diagrammatic view of the gear assembly and drive for the upper roller and wash belt beater, as driven by the water motor.

Figure 5 is a longitudinal cross-section on the line 5-5 of Figure 1, sections being broken out at each end.

Figure 6 is a longitudinal section on the line suitable elongated housing of light metal, repre- I sented generally at 5, and which is roughly tri angular on an end view. The housing includes bottom plate I, angularly formed end plates 8,

' an oblong top-plate 6, an irregularly corrugated left open as indicated at 5a, and a rectangular opening 8a is formed in the left end plate and adapted to be closed by a closure plate 8b secured in place by screws II, I I I A partition I2 is rigidly mounted in the housing 5,.in slightly spaced relation to the right end 8, to form a gear housing I3 and roller stub-shafts I4 are journaled at I6 through this partition, in a spaced relation adjacent the top plate 6, the inner. ends of these shafts being splined as shown at I]. Bearing studs or pintles I8, I9 are rigidly set in spaced relation on the inner side of the closure plate 8b, these pintles being arranged for transverse alignment with the stub shafts I4, when the plate 81) is properly secured in place over the opening 8a of the end plate .8. A pair of belt supporting rollers 28, 2|, formed with soft rubber peripheries and having bearing thimbles or sleeves 22, 23 set axially in their ends, are provided for mounting upon the stub-shafts I4, and pintles I8, I9. The thimbles 22, 23 designed for positioning over the splined shafts I4, are slotted longitudinally as at 24 for engaging the splines I1, whereby the rollers are rotated with the said stub shafts.

Undercut mortises 25 areformed on the inner sides of the left end plate 8 and the partition I2 in alignment with the rollers 28, 2|, these mortises opening out rearwardly, and a pair of bearing blocks 26 are slidably mounted in these mortises, the blocks having aligned bearing pintles 21 set onto their inner sides; A ,Wringer roller 128, similar to the rollers 20,2I, and having the bearing thimbles 29set axially into its ends, is journaled by said thimbles upon the pintles 21, and adapted to peripherally contact the inner roller 20 which in this'relation acts. as a complemental wringer roller.

An endless cleanser belt 38,. of suitably soft and porous fabric, is trained over the rollers 20, 2| for travel between the wringer rollers 20, 28. againstthe roller 28 by forming sockets 3| in the blocks 26 and passing thumb-screws 32 through thread-ed bores 91)! in the plate 9 and then setting coil springs/33 over the screws between the blocks 26 and plate 9. The casing of a suitable water motor 34 is bolted at as to the outer side of the partition I2, spaced below the rollers 20, 2|, with the left end 31 of the motor shaft 36 journaled through the partition I2 as shown at 38 and extended through the housing 5 and journaled in the left end plate 8, as shown at 39.

The roller 28 may be adjustably set An opening 90 is formed medially through the rear housing plate 9a, short sleeves 46 are rigidly mounted in transverse alignment at either side of this opening. A tubular T-joint JLhas its branches 41a, 47b snugly but ro'tatably pivoted at either side, in the sleeves 46; the hollow stem 41c" extending outwardly. The sleeves 46 open at it passes and then flows down the branches of the T-joint 4'l'and out through the hollow handle 48 alongside the feed-pipe 50, the waste water being taken care of in any convenient manner. The motor is arranged to traverse the belt 30 inwardly at its lower side, as indicated by the arrows. The motor operates the inner roller 20, which being in frictional contact with the wringer roller 28, with the belt 30 running between, the water is squeezed from the belt continuously as it enters between these rollers. The motor also simultaneously operates the beater blades 40, for

beating and jarring dirt from the cleansing belt 30. The implement is held up vertically by the handle, and the exposed peripheral portion of thewindow contact roller 2 I, as exposed through the open frontal side 5a of the housing 5, is positheir outer ends into the housing 5, and the joint 46a is so formed and rounded at either ,sideand fitted so snugly to the contacting marginsof the platefid, that water cannot pass from the housing 5' outwardly of the jointv 46a, but must flow through said joint.- A hollow or tubular handle 48 is snugly slip-jointed at 48a to .the stem 410 of the T-joint 41, and additional tubular lengths of handle (not shown) may be similarly connected, as required. Avalve controlled water feed pipe or hose 50, (the valve not shown) of'substantially smaller exterior diameter than the interiordia'meter of the'handle-dli', is passed up through the handle 48, through the right branch 41a of the T- 'joint 41 and is connected at its'end by the joint 50a through an opening 12a in the partition I2 with the intake side of the water'motor 344. -A water discharge pipe 5| is connected to the discharge side of the motor, an'd thence turned inwardly and extended through an opening IIZb in the partition [2 between the rollers 20, 2| and within the belt 30, for'discharging water upon the lower side of said belt. If desired .a'cuwed water shield 52 may be installed over the discharge extension pipe 5!, the ends of this shield being attached at its left end 52a'to; the end plate :8 and at its right end to the partition l2; .Alhandle adjustmentbar 53 maybe pivotally mounted at one, endas indicated at 53a, to the plate 9, the freeendcarrying a pawl 53b, adapted to engage any one of a series of ratchet notches 54a on 1 the plate 54 mounted at 55' to the outer side of the T-joiht 41. Bythis arrangement the angular extension of the handle 48 relative to the housing 5 may be regulatedto suit. r In-operation water or any cleansing solutionis fed through the feed pipe or hose -5ll,l to and through the motor 34, and'thence is discharged upon the lower-side of the belt 30, through which tioned upwardly on the window W, and then is drawn downwardly. The traveling cleansing belt 30 picks up the dirt from the window and carries. it inside thev housing and there discharges it in 'theima'nner pointed out above. The window is thoroughly cleaned and left comparatively dry, with no surplus liquid left to run down over the window frame and discolor same. The rollers 20, 2|.may be removed through the end opening 8a. for renewal of the belt3il.

While I have here shown and described a specific embodiment of the invention and certain structural features thereof, 'thesame may be changed or modified in details within the scope of the claims.

l I claim: V 1.- A window cleaner comprising a housing open at one side, a pair of belt rollers journaled in the housing inspaced, parallel alignment, one of the rollers protruding at 7 its periphery partially through the open side of the housing, the inner roller serving also'as a wringer roller, an endless cleansing belt mounted over the rollers, another wringer roller journaled in the housing outwardly of and in contact with the inner wringer roller andcleansing belt thereon, a water motor mountedin the housing, gear connections between the motor and the rollers for operating the latter, a hollow, drained handle for the housing, a-relatively small feed pipe extended up through .the handle into the housing and operatively connected with the intake side of the'motor, a discharge pipe connected with the discharge side of the motor and extended between the belt rollers within the belt thereon.

2. In the structure as defined in claim 1, a bel beater rotatably mounted in the housing and operatively geared to the water motor. Y
